Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A seat system of an aircraft or spacecraft, the seat system comprising: a first seat which comprises a headrest, a front side of the headrest being adapted to support a head of a first passenger and a rear side of the headrest being oriented toward a second seat located behind the first seat; and a loudspeaker device which comprises at least one pair of loudspeakers which are spaced apart from one another and arranged at the rear side of the headrest of the first seat, wherein the loudspeaker device is adapted to emit signals that are audible in a listening region in which a head of a second passenger seated in the second seat is positioned.
An aircraft or spacecraft seat system includes a first seat with a headrest designed to support a passenger's head. The back of the headrest faces a second seat. A loudspeaker system, consisting of at least two speakers, is mounted on the back of the first seat's headrest. These speakers are positioned to emit sound that is clearly audible to a second passenger sitting in the seat behind the first seat. The system creates a personal audio zone for the rear passenger without disturbing others.
2. The seat system according to claim 1 , wherein the pair of loudspeakers is located at the sides of the passenger's head and inclined towards the passenger's head in such a way that the pair of loudspeakers transmits signals towards a region in which the passenger's head is intended to be positioned.
In the aircraft seat system, the loudspeaker pair is positioned on either side of the passenger's head in the second seat, angled inward towards the head. This directs the sound signals specifically toward the area where the passenger's head would be located, enhancing the listening experience for that passenger by providing a focused audio output.
3. The seat system according to claim 1 , wherein the seat system comprises a control device which is designed to control the pair of loudspeakers such that the signals emitted by the loudspeakers are audible in a listening region in which the passenger's head is intended to be positioned.
This aircraft seat system contains a control device that manages the loudspeaker pair. The control device ensures that the sound emitted by the speakers is only clearly audible within a defined listening zone where the second passenger's head is located in the second seat. This system focuses the audio experience for the intended listener.
4. The seat system according to claim 1 , wherein the control device is designed to control the pair of loudspeakers so as to create a suppression region adjacent to the listening region, the signals emitted by the pair of loudspeakers not being audible in this suppression region.
The aircraft seat system's control device for the loudspeaker pair is engineered to create a "quiet zone" surrounding the primary listening area in the second seat. The audio emitted by the speakers is suppressed in this zone, ensuring that sound is not clearly audible outside the intended listening area of the second passenger and minimizing disturbance to others nearby.
5. The seat system according to claim 1 , wherein the loudspeaker device is connected to the headrest of the first seat by a cover.
In the aircraft seat system, the loudspeaker system is attached to the first seat's headrest using a cover. This cover provides a neat and integrated appearance, concealing the speakers and their wiring while securing them in place.
6. The seat system according to claim 1 , wherein the loudspeaker device is designed as an integral part of the first seat.
In the aircraft seat system, the loudspeaker system is built directly into the structure of the first seat. This means the speakers are not an add-on but are a designed part of the seat itself, making the integration seamless and potentially more durable or aesthetically pleasing.
7. The seat system according to claim 1 , wherein a second pair of loudspeakers is located on the second seat at the sides of the passenger's head and inclined towards the passenger's head in such a way that the second pair of loudspeakers transmits signals towards the region in which the passenger's head is intended to be positioned.
The aircraft seat system includes a second set of speakers located on the second seat’s headrest. These speakers are positioned on either side of the passenger's head and are angled inwards, directing sound specifically to where the second passenger's head will be. This provides a personalized audio experience for the passenger in the second seat, similar to the first seat's setup.
8. The seat system according to claim 7 , wherein the second pair of loudspeakers is connected in the region of the headrest of the second seat by a cover.
In the aircraft seat system, the second pair of speakers on the second seat's headrest is integrated using a cover. This cover conceals the speakers and wiring, providing a clean and finished look to the audio system within the headrest of the second seat.
9. The seat system according to claim 1 , wherein audio signals are provided to the pair of loudspeakers by an electronic device which is supplied by the passenger.
In the aircraft seat system, the audio signals for the speaker pair are provided by an electronic device brought by the passenger, such as a smartphone or tablet. The system allows passengers to connect their own devices and listen to their preferred audio through the integrated speakers, offering a personalized entertainment experience.
10. The seat system according to claim 1 , wherein a detection unit for detecting whether a seat position is occupied is provided and interrupts a production of the listening region as soon as the detection unit detects that the first seat is not occupied.
The aircraft seat system incorporates a sensor that detects whether the seat is occupied. If the sensor determines the first seat is empty, the system automatically disables the sound output from the speaker system behind the first seat. This prevents unnecessary audio output when no one is present to listen in the second seat, conserving power and reducing potential noise.
11. A cover of an aircraft or spacecraft, the cover comprising: a loudspeaker device according to claim 1 , which is connected to the cover.
A cover designed for use in an aircraft or spacecraft is integrated with a loudspeaker system. The loudspeaker system includes at least one pair of speakers, spaced apart from each other. The cover is designed to hold and support this speaker system, integrating audio functionality directly into the cover itself, presumably for attachment to a seat or headrest.
12. The cover according to claim 11 , wherein the pair of loudspeakers is located at the sides of the passenger's head and inclined towards the passenger's head in such a way that the pair of loudspeakers transmits signals towards a region in which the passenger's head is intended to be positioned.
The cover designed for aircraft or spacecraft contains a loudspeaker pair that is positioned on either side of the passenger's head and angled inward towards the head. This directs the sound signals specifically towards the area where the passenger's head would be, enhancing the listening experience by providing a focused audio output.
13. The cover according to claim 11 , wherein the cover comprises a control device which is designed to control the pair of loudspeakers such that the signals emitted by the loudspeakers are audible in a listening region in which the passenger's head is intended to be positioned.
The aircraft or spacecraft cover incorporates a control device that manages the loudspeaker pair. The control device ensures that the sound emitted by the speakers is only audible within a defined listening zone where the passenger's head is located. This system focuses the audio experience for the intended listener using the integrated speakers within the cover.
14. The cover according to claim 13 , wherein the control device is designed to control the pair of loudspeakers so as to create a suppression region adjacent to the listening region, the signals emitted by the pair of loudspeakers not being audible in this suppression region.
The aircraft cover's control device for the loudspeaker pair creates a "quiet zone" around the primary listening area. Audio from the speakers is suppressed in this zone, so it's not audible outside the intended listening area and minimizing disturbance to others nearby when used with the cover.
15. An aircraft or spacecraft comprising: a seat device comprising: a seat which comprises a headrest; and a cover comprising a loudspeaker device according to claim 1 .
An aircraft or spacecraft contains a seat device with a seat and headrest. The aircraft also has a cover with an integrated loudspeaker system including at least one pair of speakers that are spaced apart from each other, as described in the first claim. The cover integrates the sound system into the seat.
